MEANS FOR CONVERTING OSCILLATORY MOVEMENT INTO RECIPBOCATORY MOVEMENT.

Application filed May 4, 1915.

To all whom it may concern:

Be it known that I, JAMES BRUCE, a citizen of the United States,residing at Oklahoma city, in the county of Oklahoma and State ofOklahoma, have invented certain new and useful Improvements in Means forConverting Oscillatory Movement into Reciprocatory Movement; and I dohereby declare the following to be a full, clear, and exact descriptionof the invention, such as will enable others skilled in the art to whichit appertains to make and use the same.

This invention relates to a device for converting oscillatory movementinto reciprocatory movement, and the primary object of the invention isto provide a device as specified, which may be utilized for operatingwater, air, oil or like pumps, air compressors or analogous mechanicaldevices wherein a reciprocatory movement of a rod or piston is necessaryfor enabling the device to perform its function.

With the foregoing and other objects in view this invention consists insuch novel features of construction, combination and arrangement ofparts as will be hereinafter more fully described, illustrated in theaccompanying drawings and claimed.

In describing the invention in detail ref erence will be had to theaccompanying drawings wherein like characters designate like orcorresponding parts throughout the several views, and in which Figure 1is a side elevation of the improved mechanism for converting oscillatorymovement into reciprocatory movement, Fig. 2 is an edge view of thedevlce, Fig. 3 is a sectional view of the device, Fig. 4 is a crosssection on the line 4.i of Fig. 3.

Referring more particularly to the drawings, 1 designates the supportingstructure of the mechanism, which includes a pair of standards 2 and 3,which have their lower ends connected by a suitable head or block 4c.The standards 2 and 3 have a pin or shaft 5 carried by their upper ends,upon which is eccentrically mounted a disk 6. The disk (3 has a handle 7secured thereto, by a T-iron 8 and a straight metallic strap 9. The T-iron 8 is secured to one side of one end of the handle 7 and one side ofthe disk 6, and the metallic strap 9 is secured to the opposite side ofthe handle 7 and the disk 6. The handle 7 projects radially from theperiphery of the disk 6, and is provided for Specification of LettersPatent.

moving the disk upon its eccentric pivotal support. The disk 6 isprovided with a recess 10 formed in the periphery thereof, in whlch ismounted a slip ring 11. The ring 11 is loosely mounted in the annularrecess 10 and is held against accidental removal therefrom, by the sizeof the ring. The slip ring 11 is constructed of a strip of metal, and ithas its ends 12 and 13 extending out wardly therefrom, being spaced fromeach other, as is clearly shown in Figs. 1 and 2 of the drawings. Thespaced ends 12 and 13 of the slip ring 11, have a pitman rod 14 securedthereto, which extends downwardly between the standards 2 and 3 and ispivotally connected to the piston rod 15. The piston rod 15 is slidablymounted in a sleeve 16, which is carried by and extends through theblock or head 4. The piston rod 15 may be connected to the pitman rod14, by having its end reduced, as is shown at 17, and seated betweenarms 18 and 19 formed upon the lower end of the pitman rod, bybifurcating the same, or in any other desired manner.

The oscillatory movement of the handle 7, will move the disk 6 upon itseccentric pivotal connection, and will move the slip ring 11 therewith.By the loose mounting of the slip ring within the annular peripheralrecess 10, a reciprocatory movement will be imparted to the piston rod15, through the connection between the slip ring' and the piston rod, bymeans of the pitman 14;.

In reducing the invention to practice, certain minor features ofconstruction, combination and arrangement of parts may necessitatealterations, to which the patentee is entitled, provided suchalterations are com prehended within the scope of what is claimed.

lVhat is claimed is In a device of the class described including asupporting structure having a base, a pair of vertical parallel spacedstandards secured to the base, a shaft journaled through the upper endsof said standards, a disk provided with an annular peripheral grooveeccentrically mounted upon said shaft, T-shaped metallic straps securedby their crossheads to opposite faces of said disks their stemsprojecting beyond the periphery of the disk, a handle secured in theends of said stems of the straps, a ring pivotally mounted in theannular recess, the ends of said ring being spaced apart and extendingparallel from said disk, a pitnian rod removably secured between theparallel ends of said ring and extending downwardly therefrom, andlocated between the standards, a piston rod projecting through the baseof said standards, a sleeve surrounding said piston rod, the upper endof said piston rod connected to the lower end of the 10 pitrnan rodwhereby upon oscillatory movement of the handle the same imparts motionto the disk, and a reciprocating motion will be given to the pitlnan rodand the piston substantially as set forth.

In testimony whereof I afliX my signature 15 Copies of this patent maybe obtained for five cents each, by addressing the Commissioner ofPatents. Washington, I). G.
